Design of urban loop roads taking one-way traffic as main public traffic and reverse driving as auxiliary traffic

Abstract

The invention discloses a design of urban loop roads taking one-way traffic as main public traffic and reverse driving as auxiliary traffic. The one-way traffic is a method which solves the urban traffic congestion, improves the traffic capacity and is economical and effective. The arrangement of loop road one-way traffic is different from that of ordinary road one-way traffic, and the loop road one-way traffic requires the closure of an entrance and an exit of a guardrail at one side of loop roads, which results in the idling of connecting facilities outside the loop roads. Accordingly, the invention adopts the following scheme for the full utilization of resources of the original loop road traffic structure facilities and the embodiment of public traffic priority: one-way driving roads occupy three fourths in the width of the loop roads; a special reverse driving road for public transport vehicles occupies a quarter in the width of the loop roads; a side road at one side of the reverse driving road is widened by about one time; and the loop roads can be arranged in dual combination according to a one-way loop road to meet demands of various traffic directions when a city has multi-layer loop roads.

Description

1. Technical field [0001] The invention relates to a design of an urban ring road with one-way traffic as the main part and public traffic running in the opposite direction as the supplement, and the purpose is to relieve traffic jams. 2. Background technology [0002] Most of the large cities in our country adopt the traffic road network with ring-shaped radiation as the main body, and now they all suffer from different degrees of traffic troubles. It is the age of the automobile that shows that the operation mode of the fast loop is fragile, involving the traffic jam phenomenon of the loop and the road network in the whole city, exposing the disadvantages of two-way driving on multiple loops that are too close and multi-layered and narrow, resulting in time-consuming vehicles traveling on the loop Delays increase the interweaving interference of vehicles. For example, in Beijing, it is more prominent that the ring road and the auxiliary road are parallel, so that the inter...

Problems solved by technology

Practice has proved many times that without careful selection of transportation demand management and supply methods, simply adding and expanding roads cannot solve the problem of traffic congestion and low-efficiency operation in large cities
